Sir G, u really need to review ur knowledge about cars and engines.
1-Engine capacity matters, so does the technology. There is a LOT of difference b/w alto and vti.
2-Ur alto wasn't in good nick, nor were ur two VTis. Alto gives more than 120km per cylinder, I know that.
and my 1300cc idsi gives me 150kms+ in 100% local drive. How do u compare THAT with alto...?
